Description

La présente invention se rapporte à un terminal de radiocommunication où la consommation d'une puce auxiliaire multimédia intégrée au terminal est optimisée de sorte à augmenter l'autonomie du terminal en mode veille.The present invention relates to a terminal for radiocommunication where the consumption of a chip multimedia auxiliary integrated in the terminal is optimized to increase the autonomy of the terminal sleep mode.

L'invention se rapporte donc plus particulièrement au domaine des télécommunications et notamment au domaine des terminaux de radiocommunication de type GSM (acronyme pour l'expression anglo-saxonne « Global System Mobil ») susceptibles de mettre en oeuvre des fonctions de type multimédia.The invention therefore relates more particularly in the field of telecommunications and especially in the field of terminals GSM type radio communication (acronym for the Anglo-Saxon expression "Global System Mobil") likely to implement type functions multimedia.

La figure 1 montre un tel terminal de radiocommunication 10, comprenant essentiellement une antenne de réception 11, un écran 12, typiquement un écran à affichage par cristaux liquides, une touche de navigation 13 et un pavé de touches 14. Le terminal 10 comprend en plus une batterie 15 intégrée et une fiche de connexion 16 pour la connexion de la batterie avec un chargeur de batterie. Enfin, le terminal 10 comprend un circuit imprimé IMP pour accueillir l'ensemble des circuits du terminal de radiocommunication parmi lesquels des puces de microprocesseur de différents types.Figure 1 shows such a terminal radiocommunication 10, essentially comprising a receiving antenna 11, a screen 12, typically a LCD screen, one touch navigation 13 and a keypad 14. Terminal 10 additionally includes a built-in battery and a plug 16 for connecting the battery with a battery charger. Finally, terminal 10 includes an IMP printed circuit to accommodate all radiocommunication terminal circuits among which microprocessor chips from different kinds.

En effet, dans une architecture classique de terminaux de radiocommunication de type GSM, l'écran de type écran à affichage par cristaux liquides est géré par un microprocesseur réalisé sur une puce appelée la puce GSM, qui permet d'afficher à l'écran les barres de champs, l'état de la batterie etc..., et permet éventuellement de faire tourner des jeux. De plus, pour mettre en oeuvre des fonctions de type multimédia par l'intermédiaire de terminaux de radiocommunication GSM, il existe des composants spécifiques appelés puces auxiliaires multimédia MMCC (pour « Multimedia Companion Chip »). De tels composants sont dotés de très fortes capacités de traitement du signal pour permettre la gestion d'applications multimédia de type audio ou vidéo par exemple.Indeed, in a classical architecture of GSM type radio terminals, the liquid crystal display type is managed by a microprocessor made on a chip called the GSM chip, which allows the bars to be displayed on the screen fields, battery status etc ..., and allows possibly to run games. In addition, for implement multimedia type functions by through GSM radio terminals, there are specific components called chips MMCC multimedia auxiliaries (for "Multimedia Companion Chip ”). Such components are provided with very strong signal processing capabilities for allow the management of multimedia type applications audio or video for example.

Le problème technique qui se pose alors concerne la gestion de l'écran à affichage par cristaux liquides lorsqu'une puce auxiliaire multimédia MMCC est intégrée à une architecture classique de terminaux GSM. En effet, on a alors deux microprocesseurs qui doivent cohabiter pour traiter les informations liées à la gestion de l'écran.The technical problem which then arises concerns management of the liquid crystal display screen when an MMCC multimedia auxiliary chip is integrated to a classic architecture of GSM terminals. In indeed, we then have two microprocessors which must cohabit to process information related to screen management.

Or, les puces auxiliaires nécessitant des performances d'affichage accrues, elles sont directement connectées à un écran et ce sont donc ces composants qui gèrent les accès à l'écran. Ainsi est-il communément admis que la puce auxiliaire multimédia doit piloter le module de commande de l'écran à affichage par cristaux liquides du terminal de radiocommunication GSM. Pour ce faire, de tels composants possèdent donc généralement une RAM interne correspondant à l'image de l'écran et leur permettant de mettre en oeuvre leur traitement d'image. However, the auxiliary chips requiring increased display performance they are directly connected to a screen and so these are components that manage screen access. So is it commonly believed that the multimedia auxiliary chip must control the screen control module at liquid crystal display of the terminal GSM radio communication. To do this, such components therefore generally have an internal RAM corresponding to the screen image and allowing them to implement their image processing.

La figure 2 montre une telle architecture où une puce auxiliaire multimédia 1 est connectée à une puce GSM 2 par l'intermédiaire d'une liaison série, la puce GSM 2 étant prévue pour gérer les fonctionnalités classiques liées au protocole GSM. Une liaison bus parallèle est prévue pour assurer le transfert d'informations entre la puce auxiliaire multimédia 1 et un module de commande 3 qui gère l'écran à affichage par cristaux liquides du terminal de radiocommunication mobile.Figure 2 shows such an architecture where a multimedia auxiliary chip 1 is connected to a chip GSM 2 via a serial link, the chip GSM 2 being provided to manage the functionalities GSM protocol classics. A bus link parallel is provided to ensure the transfer information between the multimedia auxiliary chip 1 and a control module 3 which manages the display screen by liquid crystal of the radiocommunication terminal mobile.

On sait que l'économie d'énergie est un enjeu crucial pour les fabricants de terminaux de radiocommunication GSM et cet enjeu se traduit notamment par un souci d'optimiser au mieux l'autonomie en mode veille des terminaux de radiocommunication, le mode veille se caractérisant par une simple écoute du réseau, le terminal n'émettant rien. Cependant, quand le terminal de radiocommunication mobile est en mode veille, l'écran à affichage par cristaux liquides doit être rafraíchi régulièrement avec des informations concernant notamment l'état du réseau, l'état de la batterie, etc...We know that saving energy is an issue crucial for terminal manufacturers of GSM radio communication and this issue is translated in particular by a concern to optimize autonomy as much as possible in standby mode of the radiocommunication terminals, the standby mode characterized by simple listening to the network, the terminal transmitting nothing. However, when the mobile radio terminal is in mode standby, the LCD screen should to be refreshed regularly with information concerning in particular the state of the network, the state of battery, etc ...

Or, on a vu que l'intégration d'une puce auxiliaire multimédia dans un terminal de radiocommunication GSM aboutit à l'architecture de la figure 2, où le module de commande de l'écran est piloté par la puce auxiliaire multimédia.However, we have seen that the integration of a chip multimedia auxiliary in a terminal GSM radio communication leads to the architecture of Figure 2, where the screen control module is controlled by the multimedia auxiliary chip.

Selon la norme GSM, il est stipulé qu'une écoute du réseau doit être réalisée toutes les 2,5 secondes en moyenne. Ainsi, lorsque le terminal de radiocommunication est en mode veille, la puce GSM a potentiellement des informations à transmettre à la puce auxiliaire multimédia toutes les 2,5 secondes.According to the GSM standard, it is stipulated that listening of the network must be performed every 2.5 seconds in average. So when the terminal of radio communication is in standby mode, the GSM chip has potentially information to be transmitted to the multimedia auxiliary chip every 2.5 seconds.

La puce auxiliaire multimédia doit alors sortir de l'état de veille pour mettre en oeuvre l'opération de rafraíchissement de l'écran à affichage par cristaux liquides. Dans tous les autres cas, des modes de mise hors tension de la puce auxiliaire sont mis en oeuvre. La puce auxiliaire désactive alors toutes ses ressources non nécessaires et reste en mode veille.The multimedia auxiliary chip must then come out from the standby state to implement the operation to refresh the crystal display screen liquids. In all other cases, betting methods off the auxiliary chip are implemented. The auxiliary chip then deactivates all of its resources not needed and remains in standby mode.

Néanmoins, comparé à une architecture d'un terminal de radiocommunication mobile classique où la puce GSM pilote directement l'écran à affichage par cristaux liquides par l'intermédiaire de son module de commande, l'architecture illustrée à la figure 2 d'un terminal de radiocommunication mobile « intelligent » où une puce auxiliaire multimédia est intégrée impose donc de mettre sous tension la puce auxiliaire multimédia même quand le terminal est en mode veille pour rafraíchir l'écran à affichage par cristaux liquides.Nevertheless, compared to an architecture of a conventional mobile radio terminal where the GSM chip directly controls the display screen by liquid crystals through its module command, the architecture illustrated in Figure 2 of a “intelligent” mobile radio terminal where a multimedia auxiliary chip is integrated requires so turn on the auxiliary chip multimedia even when the terminal is in standby mode to refresh the crystal display screen liquids.

Ainsi, le fait de mettre sous tension la puce auxiliaire multimédia avec ses mémoires pour permettre l'affichage à l'écran d'informations qui concernent l'état du réseau alors que la puce auxiliaire est spécifiquement prévue pour traiter des informations de type multimédia a pour conséquence d'augmenter notablement la consommation d'énergie (notamment à cause des courants de fuite) pendant la durée du mode veille où des opérations de rafraíchissement de l'écran doivent être mises en oeuvre. So, powering up the chip multimedia auxiliary with its memories to allow the display of information relating to network status while the auxiliary chip is specifically intended to process information from multimedia type has the consequence of increasing notably the energy consumption (notably at cause of leakage currents) for the duration of the mode standby where screen refresh operations must be implemented.

Une architecture de terminal de radiocommunication mobile telle qu'elle est représentée à la figure 2 où la puce auxiliaire multimédia pilote le module de commande de l'écran à affichage par cristaux liquides présente donc de faibles performances en terme de consommation d'énergie en mode veille du terminal.Terminal architecture of mobile radio as shown in Figure 2 where the pilot multimedia auxiliary chip the screen display control module by liquid crystal therefore has poor performance in terms of energy consumption in standby mode of the terminal.

C'est par conséquent un objet de la présente invention de pallier aux inconvénients de l'art antérieur sus-mentionnés en proposant une amélioration à l'architecture décrite à la figure 2, de sorte à fournir un terminal de radiocommunication type GSM intelligent, c'est à dire intégrant une puce auxiliaire multimédia, doté de performances de consommation d'énergie en mode veille équivalentes à celles d'un terminal de radiocommunication mobile standard.It is therefore an object of this invention to overcome the drawbacks of art above mentioned by proposing an improvement architecture described in Figure 2, so that provide a GSM type radio terminal intelligent, i.e. integrating an auxiliary chip multimedia, with consumer performance energy in standby mode equivalent to that of a standard mobile radio terminal.

A cet effet, l'invention prévoit d'éviter d'utiliser la puce auxiliaire multimédia lorsque le terminal de radiocommunication est en mode veille. Ainsi, en mode veille où le terminal n'est pas en communication et met simplement en oeuvre une fonction d'écoute du réseau, l'invention prévoit de désactiver la puce auxiliaire multimédia et l'écran à affichage par cristaux liquides est alors rafraíchi directement par l'intermédiaire de la puce GSM.To this end, the invention intends to avoid to use the multimedia auxiliary chip when the radio terminal is in standby mode. Thus, in standby mode where the terminal is not in communication and simply implements a function listening to the network, the invention plans to deactivate the multimedia auxiliary chip and the display screen by liquid crystals is then refreshed directly via the GSM chip.

L'invention concerne donc un terminal de radiocommunication comprenant un écran géré par un module de commande et au moins deux types différents de microprocesseur, ledit premier type de microprocesseur améliore les fonctionnalités graphiques dudit terminal et pilote ledit module de commande de l'écran, ledit second type de microprocesseur gère les autres fonctionnalités dudit terminal, lequel terminal est caractérisé en ce que pendant la durée du mode veille, ledit premier type de microprocesseur est désactivé tandis que ledit second type de microprocesseur pilote le module de commande de l'écran.The invention therefore relates to a terminal radiocommunication including a screen managed by a control module and at least two different types of microprocessor, said first type of microprocessor improves the graphic functionality of said terminal and controls said screen control module, said second type of microprocessor manages the others functionalities of said terminal, which terminal is characterized in that during the duration of the standby mode, said first type of microprocessor is deactivated while said second type of pilot microprocessor the screen control module.

D'autres caractéristiques et avantages de la présente invention apparaítront plus clairement à la lecture de la description qui suit donnée à titre d'exemple illustratif et non limitatif et faite en référence aux figures annexées dans lesquelles :

  • la figure 1 est un schéma illustrant un terminal de radiocommunication standard et a déjà été décrite ;

  • la figure 4 est un schéma illustrant un second mode de réalisation de l'invention, et
  • la figure 5 est un schéma illustrant un troisième mode de réalisation de l'invention.
Other characteristics and advantages of the present invention will appear more clearly on reading the description which follows given by way of illustrative and nonlimiting example and made with reference to the appended figures in which:
  • FIG. 1 is a diagram illustrating a standard radiocommunication terminal and has already been described;
  • FIG. 2 is a diagram illustrating the drawbacks linked to the integration of a multimedia auxiliary chip in a standard radiocommunication terminal architecture and has already been described;
  • FIG. 3 is a diagram illustrating a first embodiment of the invention;
  • FIG. 4 is a diagram illustrating a second embodiment of the invention, and
  • Figure 5 is a diagram illustrating a third embodiment of the invention.

On retrouve aux figures 3, 4 et 5 les mêmes éléments que ceux déjà décrits en référence à la figure 2. Ainsi, la figure 3 montre un premier type de microprocesseur 1 réalisé sur une puce appelée puce auxiliaire multimédia. La puce auxiliaire 1 est dédiée spécifiquement au traitement des fonctionnalités multimédia du terminal dans lequel elle est intégrée, permettant ainsi d'améliorer fortement les fonctionnalités graphiques du terminal.We find in Figures 3, 4 and 5 the same elements as those already described with reference to the figure 2. Thus, Figure 3 shows a first type of microprocessor 1 produced on a chip called a chip multimedia auxiliary. Auxiliary chip 1 is dedicated specifically to functionality processing multimedia of the terminal in which it is integrated, thus greatly improving the graphic functionality of the terminal.

Un deuxième type de microprocesseur 2 est réalisé sur une autre puce appelée puce GSM. La puce GSM 2 est en effet prévue pour traiter les autres fonctionnalités du terminal de radiocommunication dans lequel elle est intégrée et en particulier les fonctionnalités liées à la gestion du protocole GSM.A second type of microprocessor 2 is produced on another chip called a GSM chip. The GSM 2 chip is indeed intended to handle other features of the radiocommunication terminal in which it is integrated and in particular the functionalities related to GSM protocol management.

La figure 3 montre enfin un module de commande 3 de l'écran à affichage par cristaux liquides disposant à la fois d'une interface série 4 et d'une interface parallèle 5. Dans ce premier mode de réalisation de l'invention, les deux types de microprocesseur 1 et 2 sont chacun connectés au module de commande 3 de l'écran à affichage par cristaux liquides. La puce GSM 2 ayant le moins d'informations à transmettre est connectée à l'interface série du module de commande 3 par l'intermédiaire d'une liaison bus série 6, tandis que la puce auxiliaire multimédia 1 est connectée à l'interface parallèle du module de commande 3 par l'intermédiaire d'une liaison bus parallèle 7, la puce GSM 2 et la puce auxiliaire multimédia 1 étant également connectées ensemble par l'intermédiaire d'une ligne de transmission de données 8. A un instant donné, on considère qu'il n'y a qu'un seul type de microprocesseur maítre du module de commande de l'écran à affichage par cristaux liquides.Figure 3 finally shows a control module 3 liquid crystal display screen both a serial 4 interface and an interface parallel 5. In this first embodiment of the invention, the two types of microprocessor 1 and 2 are each connected to the control module 3 of the liquid crystal display screen. GSM chip 2 having the least information to transmit is connected to the serial interface of the control module 3 via a serial bus link 6, while that the multimedia auxiliary chip 1 is connected to the parallel interface of the control module 3 by via a parallel bus link 7, the chip GSM 2 and the multimedia auxiliary chip 1 being also connected together through a data transmission line 8. At a given time, we consider that there is only one type of screen control module master microprocessor with liquid crystal display.

Dans cette configuration, notamment pour les applications de type multimédia, le module de commande de l'écran à affichage par cristaux liquides est piloté par la puce auxiliaire multimédia 1, la puce GSM étant quant à elle prévue pour gérer les autres fonctionnalités du terminal. Les informations concernant notamment l'affichage des barres de champ, l'état de la batterie etc... qui sont classiquement traitées par la puce GSM 2 sont alors transférées vers la puce auxiliaire 1 par l'intermédiaire de la ligne de transmission de données 8 de sorte à ce que la puce auxiliaire 1 commande l'affichage de ces informations à l'écran.In this configuration, especially for multimedia applications, the control module of the liquid crystal display screen is controlled by the multimedia auxiliary chip 1, the GSM chip being meanwhile planned to manage others terminal functionality. Information concerning in particular the display of field bars, the state of the battery etc ... which are conventionally processed by the GSM 2 chip are then transferred to the auxiliary chip 1 via the line of data transmission 8 so that the chip auxiliary 1 controls the display of this information to the screen.

Cependant, lorsque le terminal passe en mode veille, c'est à dire qu'il est simplement en écoute du réseau, l'utilisateur ayant décidé d'arrêter les applications multimédia en cours, la puce GSM 2 devient seule maítre du module de commande 3 de l'écran par l'intermédiaire le la liaison bus série 6. Ainsi, en mode veille, il n'y a que la puce GSM 2 qui travaille. Auquel cas, un transfert d'informations doit être réalisé avant de désactiver la puce auxiliaire multimédia 1, de la puce auxiliaire 1 vers la puce GSM 2 par l'intermédiaire de la ligne de transmission de données 8, de sorte que la puce GSM récupère le contexte dans lequel se trouvait l'écran du terminal avant qu'elle ne prenne la main et pilote à son tour le module de commande de l'écran.However, when the terminal enters mode standby, that is, he is simply listening to the network, the user having decided to stop multimedia applications in progress, the GSM 2 chip becomes sole master of the screen control module 3 by through the serial bus link 6. So, in standby mode, only the GSM 2 chip works. In which case, a transfer of information must be before deactivating the auxiliary chip multimedia 1, from the auxiliary chip 1 to the GSM chip 2 via the transmission line of data 8, so that the GSM chip retrieves the context in which the terminal screen was located before it takes the hand and pilot in turn the screen control module.

La puce auxiliaire multimédia ainsi que ses mémoires, peut donc être désactivée en mode veille, autorisant ainsi de meilleures performances en terme d'économie d'énergie. Un mécanisme de désactivation est donc mis en oeuvre pour partager le module de commande de l'écran à affichage par cristaux liquides entre la puce GSM, lorsque le terminal est en mode veille, et la puce auxiliaire multimédia dans tous les autres cas, ce qui permet d'augmenter l'autonomie en veille du terminal ou du moins de la rendre équivalente à celle d'un terminal de radiocommunication standard ne mettant pas en oeuvre de puce auxiliaire multimédia.The multimedia auxiliary chip and its memories, can therefore be deactivated in standby mode, thus allowing better performance in terms energy saving. A deactivation mechanism is therefore implemented to share the command module of the LCD screen between the GSM chip, when the terminal is in standby mode, and the multimedia auxiliary chip in all other cases, this which increases the standby time of the terminal or at least make it equivalent to that of a standard radiocommunication terminal not not using a multimedia auxiliary chip.

Il est à noter que tous les modules de commande d'écran à affichage par cristaux liquides ne possèdent pas deux types d'interface, série et parallèle, comme en référence à la figure 1, mais pour la plupart seulement une interface parallèle. La figure 4 propose alors un mode de réalisation particulier de l'invention susceptible de s'adapter à de tels modules de commande d'écran.Note that all control modules liquid crystal displays not two types of interface, serial and parallel, like with reference to Figure 1, but for the most part only a parallel interface. Figure 4 suggests then a particular embodiment of the invention capable of adapting to such control modules screen.

Le module de commande 3 de l'écran à affichage par cristaux liquides de la figure 4 possède donc une seule interface parallèle 5, ce qui implique qu'un seul circuit peut lui être connecté.The control module 3 of the display screen liquid crystal of Figure 4 therefore has a single parallel interface 5, which implies that only one circuit can be connected to it.

L'architecture de la figure 4 comprend alors en plus un multiplexeur externe 2x1 9 dont les deux entrées sont connectées respectivement, l'une au premier type de microprocesseur réalisée sur la puce auxiliaire multimédia 1, l'autre au deuxième type de microprocesseur réalisé sur la puce GSM 2, par l'intermédiaire de liaisons de type bus parallèle. La sortie du multiplexeur 9 est quant à elle connectée à l'interface parallèle du module de commande 3 de l'écran à affichage par cristaux liquides par l'intermédiaire d'une liaison de type bus parallèle. Enfin, la puce GSM 2 et la puce auxiliaire 1 sont reliées entre elles par la ligne de transmission de données 8. The architecture of Figure 4 then includes plus an external 2x1 9 multiplexer, both of which inputs are connected respectively, one to first type of microprocessor produced on the chip multimedia auxiliary 1, the other to the second type of microprocessor produced on the GSM 2 chip, by via parallel bus type connections. The output of multiplexer 9 is connected to the parallel interface of the control module 3 of the LCD screen by via a parallel bus type link. Finally, the GSM 2 chip and the auxiliary 1 chip are interconnected by the transmission line of data 8.

Le rôle du multiplexeur 9 est de gérer une priorité d'accès au module de commande 3 de l'écran entre la puce auxiliaire multimédia 1 et la puce GSM 2. Le multiplexeur 9 permet de prendre en compte soit le flux de données qui vient de la puce GSM lorsque le terminal est en mode veille, soit le flux de données qui vient de la puce auxiliaire multimédia dans les autres cas.The role of the multiplexer 9 is to manage a priority of access to control module 3 of the screen between the multimedia auxiliary chip 1 and the GSM chip 2. The multiplexer 9 makes it possible to take into account either the data stream that comes from the GSM chip when the terminal is in standby mode, i.e. the data flow which comes from the multimedia auxiliary chip in the other cases.

Pour ce faire, le multiplexeur externe 9 est commandée par une commande cde-veille, laquelle peut par exemple être pilotée par la puce GSM. Ainsi, lorsque le terminal se trouve en mode veille et que l'utilisateur décide d'arrêter les applications multimédia en cours, la commande cde-veille est appliquée au multiplexeur 9 par l'intermédiaire de la puce GSM et le flux de données pris en compte pour piloter le module de commande de l'écran est celui issu de la puce GSM 2. La puce GSM 2 pilote alors le module de commande 3 de l'écran tandis que la puce auxiliaire multimédia 1 est désactivée, ce qui permet d'optimiser la consommation d'énergie du terminal en mode veille. Préalablement à sa désactivation, la puce auxiliaire 1 transfère des informations à la puce GSM 2 par l'intermédiaire de la ligne 8 de sorte que la puce GSM 2 récupère le contexte dans lequel se trouvait l'écran avant qu'elle ne prenne la main pour piloter à son tour l'écran.To do this, the external multiplexer 9 is controlled by a command from standby, which can for example be controlled by the GSM chip. So, when the terminal is in standby mode and the user decides to stop the applications multimedia in progress, the command cde-standby is applied to multiplexer 9 through the GSM chip and the data flow taken into account for control the screen control module is the one from GSM 2 chip. The GSM 2 chip then drives the module 3 screen control while the auxiliary chip multimedia 1 is deactivated, which optimizes the power consumption of the terminal in standby mode. Before deactivation, the auxiliary chip 1 transfers information to the GSM 2 chip by through line 8 so the GSM chip 2 retrieves the context in which the screen was located before she takes the hand to pilot in turn the screen.

Inversement, lorsque le terminal n'est plus en mode veille ou que l'utilisateur lance des applications multimédia, la commande cde-veille n'est pas appliquée au multiplexeur 9 et le flux de données pris en compte par le multiplexeur sera celui issu de la puce auxiliaire multimédia 1 qui va alors piloter le module de commande 3 de l'écran. Quand la puce auxiliaire 1 est activée, des données sont transmises sur la ligne 8 de la puce GSM 2 vers la puce auxiliaire 1 qui pilote dorénavant l'écran de façon à tenir compte des informations classiquement traitées par la puce GSM concernant les barres de champs, l'état de la batterie etc...Conversely, when the terminal is no longer in standby mode or the user launches applications multimedia, cde-standby command is not applied to multiplexer 9 and the data flow taken into account by the multiplexer will be the one from the chip multimedia auxiliary 1 which will then control the module screen 3. When the auxiliary chip 1 is activated, data is transmitted on line 8 from the GSM 2 chip to the auxiliary chip 1 which controls from now on the screen so as to take into account information conventionally processed by the GSM chip concerning the field bars, the state of the battery etc ...

Enfin, le mode de réalisation de la figure 5 illustre une variante du mode de réalisation qui vient d'être décrit en référence à la figure 4. Dans cette variante, une évolution de la puce GSM classique est mise en oeuvre dans un souci d'utiliser le minimum de composant. Ainsi, le multiplexeur 9 de la figure 4 est avantageusement intégré à la puce GSM 2, laquelle doit alors comprendre des entrées/sorties supplémentaires. Néanmoins, les connexions entre les différents composants restent identiques par rapport à la figure 4. L'intégration du multiplexeur 9 à la puce GSM 2 ne modifie donc en rien le fonctionnement tel qu'il a été décrit en référence à la figure 4 mais permet par contre d'optimiser davantage l'architecture de la figure 4 en terme de coût et de place, en plus de permettre une optimisation de l'autonomie du terminal en mode veille.Finally, the embodiment of Figure 5 illustrates a variant of the embodiment which comes to be described with reference to Figure 4. In this variant, an evolution of the classic GSM chip is implemented in order to use the minimum of component. Thus, the multiplexer 9 of FIG. 4 is advantageously integrated into the GSM 2 chip, which must then include additional inputs / outputs. However, the connections between the different components remain identical to the figure 4. The integration of the multiplexer 9 into the GSM 2 chip does not therefore in no way modifies the functioning as it was described with reference to Figure 4 but allows by against further optimizing the architecture of the Figure 4 in terms of cost and space, in addition to allow optimization of terminal autonomy sleep mode.
